Why does sizeLimit not working in AEM while dragging file from asset?

[rosudel]

I'm trying to implement sizeLimit in cq:dialog of component. But sizeLimit is working only while I upload a file. It's not working while I drag a file from asset. Can I apply sizeLimit while dragging file from asset?

<file
        jcr:primaryType="nt:unstructured"
        sling:resourceType="cq/gui/components/authoring/dialog/fileupload"
        sizeLimit="100"
        autoStart="{Boolean}false"
        class="cq-droptarget"
        fileNameParameter="./fileName"
        fileReferenceParameter="./fileReference"
        mimeTypes="[image/gif,image/jpeg,image/png,image/webp,image/tiff,image/svg+xml]"
        multiple="{Boolean}false"
        name="./file"
        title="Upload Image Asset"
        uploadUrl="${suffix.path}"
        useHTML5="{Boolean}true"/>

You can follow the suggestion given by @kautuk_sahni

you need to write a custom sling servlet that handles the upload of the asset. Before placing the content into the JCR - check to see if the size of the asset is according to your requirement. If not then reject it.

So sizeLimit = " 100000" can't be implemented while dragging file from asset to component?
